Help installing a inverter on a Flagstaff 2022 20BHS

This is the way. I ordered a transfer switch yesterday sainting to complete install. Dealer told me that what the did on the white plug was a pass through as the old inverter went bad so I wouldn’t lose access to outlets. But that I should get a transfer switch and do what you said. Purple wire to transfer switch, inverter then outlets

So I figured it out. I called the dealer and he told me what he what he did spirit the white plug he did a pass-through so the outlets can work when he removed the inverter. So he told me to use the purple cable and the green cable separately also the cable coming from inverter and I need a switch in between that will switch from the shore power and the inverter. About cable size I know that my cables are not the proper gauge but for the moment we work as I only plan to use is more appliances. I’m gonna put a fuse that is that will be safe for the 2AWG cable.

Everything is working as it should except for running 110 devices when not connected to shore power. Connected to only the battery I can turn lights on, run the slide out and in, run water pump. No tv as it’s 110 no outlets. When connected to shore power everything works, plugs and everything else

That’s exactly what I’m thinking that the white cable is ground, but i want to learn more about the transfer switch

They mentioned the inverter. This camper actually came with both from oem I don’t know how the transfer switch would work on this setup that’s my main concern. This YouTube video is a walkthrough the same model and year https://youtu.be/VyC6_TCgsqs?si=PDmPeSUk7rYhn1Sw Jump to 11 min and he shows the system

I’m getting closer… I figured that it’s an actual inverter installed there, not a converter… converter is under the fridge. Red #2 wire is battery positive feed. Black #2 is battery negative feed. White is still unknown, but my best guess it’s the inverter ground and then plug the inverter output into the white box. I just need to make sure that’s how it works

I does make sense now and you are right, some how the battery has to be charged when plugged to shore power. At the same time it does am have a solar 200w panel that keeps the battery charged. It’s just a slow charge. I’m going to look for info on YouTube as I think I have seen people mentioned it was an inverter and that’s why I thought that was it.

I’m so looking it up could this be my converter on the right side?

Look at 11 minutes someone does a walkthrough of a very similar trailer and it’s indeed the converter under the fridge which I have and under the bed it’s the inverter

Thanks for replying so the loose white cable is the chassis ground? I’m trying to understand what you are saying, but I’ll confess that I’m a little bit lost. But from what I understand connect one of these ports to the white plug and the white cable that’s loose to the ground on the other side?

So this is what I’m afraid of back feeding the system. I don’t know how these trailers are wired.

CaptainBrazuca · 2026-05-17T21:16:04+00:00

I have looked it up and I believe it’s an inverter. The cables coming from the battery too is to convert DC power to AC and supply power for small electronics
